![]() ![]() To address this problem, we first transformed the mixed integer programming problem (MIPP) into a standard convex optimization problem based on successive convex approximation (SCA) technology. We aim to maximize the sum rate by jointly optimizing the deployment of UAV and transmit power. The resource allocation of UAV relay-assisted NOMA systems is investigated in this paper with HIs. Considering the HIs, most studies are from the perspective of performance analysis. However, the impact of HIs on system performance cannot be ignored, especially in the case of high bit rates. Most existing research on resource allocation algorithms for UAV communication is considered with the ideal hardware condition. In the unmanned aerial vehicle (UAV) assisted non-orthogonal multiple access (NOMA) networks, the practical hardware impairments (HIs) and resource allocation is still a challenging problem. Additionally, the performance in terms of fairness and throughput is also superior to state-of-the-art schedulers. The results demonstrate that the proposed scheduler can achieve the required latency for H-IoT applications. The scheduler allocates the channel resources for UL transmission taking into consideration the traffic class or access category. Therefore, we propose a UL OFDMA scheduler for the next Wireless Fidelity (Wi-Fi) standard, the IEEE 802.11be, that is compliant with the latency requirements for healthcare applications. The uplink (UL) transmission during the orthogonal frequency division multiple access (OFDMA) in the wireless local area networks (WLANs) can incur a delay which may not be acceptable for delay-sensitive applications such as H-IoT due to their random nature. However, ensuring a limit on transmission delays is an essential requirement of such monitoring systems. Ambient assisted living (AAL) entails monitoring a patient’s health to ensure their well-being. The continuous monitoring of an individual’s health for disease diagnosis and early detection is an important application of H-IoT. The healthcare Internet of Things (H-IoT) is an interconnection of devices capable of sensing and transmitting information that conveys the status of an individual’s health. ![]()
